Switches for appliances - Part 2-1: Particular requirements for cord switches (IEC 61058-2-1:2018)

This document applies to cord switches (mechanical or electronic) for appliances actuated by
hand, by foot or by other human activity, to operate or control electrical appliances and other
equipment for household or similar purposes with a rated voltage not exceeding 250 V and a
rated current not exceeding 16 A.
Throughout this document, the word "appliance" means "appliance or equipment".
These switches are intended to be operated by a person, via an actuating member or by
actuating a sensing unit. The actuating member or sensing unit can be integral or arranged
separately from the switch. The transmission of a signal between the actuating member or
sensing unit and the switch can be made either physically or electrically (for example,
electrical, optical, acoustic or thermal).
Switches which incorporate additional control functions governed by the switch function are
within the scope of this document.
This document also covers the indirect actuation of the switch when the operation of the
actuating member or sensing unit is provided by a remote control or a part of an appliance
such as a door.
NOTE 1 Electronic switches can be combined with mechanical switches giving full disconnection or
microdisconnection.
NOTE 2 Electronic switches without a mechanical switch in the supply circuit provide only electronic
disconnection. Therefore, the circuit on the load side is always considered to be live.
NOTE 3 For switches used in tropical climates, additional requirements can apply.
NOTE 4 Attention is drawn to the fact that the standards for appliances can contain additional or alternative
requirements for switches.

SWITCHES FOR APPLIANCES –

Part 2-1: Particular requirements for cord switches

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC
Publication(s)"). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 61058-2-1 has been prepared by subcommittee 23J: Switches for
appliances, of IEC technical committee 23: Electrical accessories.
This third edition cancels and replaces the second edition published in 2010 and constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
Overall format to support IEC 61058-1, IEC 61058-1-1, IEC 61058-1-2, and the heating tests.

This document is to be read in conjunction with IEC 61058-1:2016.
This document supplements or modifies the corresponding clauses in IEC 61058-1, so as to
convert that publication into the IEC standard: Particular requirements for cord switches.
When a particular subclause of IEC 61058-1 is not mentioned in this document, that
subclause applies as far as reasonable. Where this document states "addition", "modification"
or "replacement", the relevant text of IEC 61058-1 is to be adapted accordingly.
In this standard:
1) the following print types are used:
• requirements proper: in roman type;
• test specifications: in italic type;
• explanatory matter: in smaller roman type.
2) subclauses, notes, figures and tables which are additional to those in IEC 61058-1 are
numbered starting from 101.
A list of all parts in the IEC 61058 series, published under the general title Switches for
appliances, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to
the specific document. At this date, the document will be
• reconfirmed,
• withdrawn,
